I used to use the Gentoo LiveCD beta2 to get acces to terminal and other stuff to install ubuntu, but i REALLY WANT to install Gentoo PowerPC and xbox360 patches in my xbox360.

The question is, how can i do it?

I'm not a noob nor a pro, but i need some help to get the installation done from scratch.

My way of thinking is..:

1- Get gentoo live cd up and running
2- Partition de HardDisk (1 swap, 1 restofdisk)
3- Start installing the system like a "from scratch" PC installation, using PowerPC packages, but, where can i found them?
4- Use Xbox360 kernel stuff&& patches, compile a kernel with a VirtualMachine with Xenon-toolchain, once it's finished, apply it to the box( don't know how to do it)
5- Create a USB or CD/DVD with the http://file.libxenon.org/latest_kern available for Xbox360 (Thinking about modifying some KBOOT.conf)
6- Try to get the system up and running like i've done with ubuntu, and Debian 6

Can anyone give me a hand to acomplish this? I have 3 Xbox360 Jtagged and i want to get profit of them.

Although emerging stuff will take longer, the "easier" way would be to emerge stuff directly on the machine. Cross-compiling can be quite bitchy and if you don't know how to fix stuff you will get frustrated quite easily. Among the things i've seen were:

1. broken configure-scripts (lots of packages just bail out when you try to cross-compile them...)
2. packages using a wild mixture of host-compiler and cross-compiler ("famous" examples are python and perl)
3. packages trying to link host-libraries
4. packages trying to use cross-compiled executables during compilation
5. Plus the usual stuff like packages not compiling, segfaulting at runtime...
